FL455K0000S003

Overview

The FL455K0000S003 is a ceramic filter manufactured by TGS, designed for AM radio frequency applications. It operates with a center frequency of 455kHz and provides a bandwidth of 7 kHz. The component features an impedance of 1.5kOhm and is housed in a 3-SMD, J-Lead package. Its physical dimensions are 6.50mm in length and 6.00mm in width, belonging to the CFTC U series.

Feature Summary

• Designed specifically for AM radio frequency signal processing
• Utilizes a compact surface-mount J-lead package configuration
• Provides defined center frequency and bandwidth characteristics

Applications

• AM radio receiver circuits
• Intermediate frequency filtering in broadcast receivers
• RF signal processing modules requiring 455kHz selection

Procurement Notes

Verify the specific datasheet version for the FL455K0000S003 to confirm exact electrical tolerances and thermal specifications before integration. Ensure compatibility with the target PCB footprint for the 3-SMD J-Lead package. Cross-reference the manufacturer's official documentation for any updates regarding material composition or environmental compliance standards relevant to the production batch.

Selection Notes

Select this component when a fixed 455kHz center frequency with 7 kHz bandwidth is required for AM reception. The 1.5kOhm impedance must match the source and load requirements of the intermediate frequency stage. The SMD form factor is suitable for automated assembly processes where space constraints necessitate the 6.50mm x 6.00mm footprint.

Part Context

This part belongs to TGS's ceramic filter portfolio, specifically the CFTC U series. These components are engineered for stable performance in consumer electronics and communication devices. The 455kHz standard is widely used in AM broadcasting superheterodyne receivers, making this filter a common choice for intermediate frequency stages in legacy and modern radio designs.

Replacement Considerations

Consult official substitution lists for equivalent ceramic filters with matching 455kHz center frequency and 7 kHz bandwidth. Verify that alternative parts maintain the 1.5kOhm impedance and compatible 3-SMD J-Lead package dimensions to ensure mechanical and electrical interchangeability without circuit redesign.
